We never sell any of our equipment, I hold onto and cherish the gear that has been accumulated over the years.
We have 10 complete enlarger systems in storage for future use , as the gear we currently use gets banged around and having backups to the backups is reassuring.
Lots of stuff gets donated to us and we try to find good homes for the equipment and use what we can. Nothing goes to the resellers of camera, darkroom gear for profit, they are not welcome in our house.
